Hello all,
Jconv-0.8.0 is now available at the usual place
<http://www.kokkinizita.net/linuxaudio/downloads>
New in this release:
- New command line option -L <nsamples>, tries
to compensate for 'nsamples' of processing
latency.
- Jack ports can now be given meaningful names
and optionally be connected, by commands in the
config files.
- Some new reverb IRs available in a separate
package 'jconv-reverbs'. Includes ambisonic and
stereo IRs of the concert hall of La Casa della
Musica, and the former Santa Elisabetta church,
now La Casa del Suono, in Parma.
Enjoy !

Nothing, I forgot you need an update of zita-convolver.
It's uploaded now.
Make sure to check the makefile for zita-convolver
and add the best optimisation flags for your CPU.

Just delete the makeald line in the install
target. I'll update the release...
(Seems like I'm trying to do too much in too little time)

wow. thanks for the new example configurations and the extensive
comments! very helpful.
the convolver itself is a bit of a marketing disaster, though. i mean,
uh, it just convolves. No fancy new features, such as UltraLowJitter, or
at least TrueMultiplyAndAdd (for purists, as opposed to FFT-based, for
that extra dash of depth and clarity). And TubeMode would be cool as
well. but one cannot have it all, i assume. ;)
in the reverb configs, you mention that you cut off the direct sound by
setting an offset, which will then make the convolutions suitable to use
in a classic "aux send" setup, so that the reverb return will be 100% wet.
but why do you remove the first 5 ms of the room response?
i seem to recall it is about control of low frequency energy, but i
forgot the details. are those 5ms a natural constant, a matter of taste,
or maybe a function of the room's rt60? pointers to TFM would be R with
great interest.
best,

:-) I'll take the IR of a long tube one if these days.

Because it's not room response but speaker response
(mainly LF, if the source was not well equalised),
or reflections from very close objects which are
not perceived as reflections but just add a nasty
colouration.

Fons,
Thanks for the update. I was up early this morning testing it, and all goes
fine.
The new AMB configs are cool, and the more extensive user friendly comments
will certainly help.
Alex.

This appears to use a version of libsndfile that has ambisonic

forked or patched version somewhere?

You can use the official release, see the Makefile
where you need to uncomment one line. The standard
libsndfile can read files with the ambisonic GUID,
so this will not affect jconv. It does affect some
unused (by jconv) functionality in the impdata class
which jconv shares with other apps.
Version 18 of libsndfile has been in pre-release
for something like two years now. You can find
it on Eric's site. If you decide to use it make
sure to take a recent one, as the AMB stuff was
broken in some older pre-release versions.

I love to keep 'em guessing :-).
Basically there's a number of ways to keep up with this. There's
a libsndfile announce mailing list,
http://www.mega-nerd.com/libsndfile/lists.html
I also announce on freshmeat and there's a libsndfile RSS feed on
my blog:
http://www.mega-nerd.com/erikd/Blog/CodeHacking/libsndfile/index.html
http://www.mega-nerd.com/erikd/Blog/CodeHacking/libsndfile/index.rss20
http://www.mega-nerd.com/erikd/Blog/CodeHacking/libsndfile/index.atom
Other than mailing individual developers, I don't see what else I can
do. Obvious Paul mainages to keep up :-)
Cheers,
Erik
PS : I do hope people realise that was tounge firmly in cheek.

Since this is such a basic (meaning essential) lib for
all things audio, maybe announce new releases on LAD ?
(Or did I miss it ?)

Well I used to that ages ago and stopped because I was releasing
quite often.
Maybe I should start again.
